, FLUSING ATTACHE/[EN T FOR SEWERS.

Patented Apr. 2, 13913.

To all whom it may concern:

Be it known that we, JOHN A. FLETCHER JOHN WESLEY HALEY, subjects of the King of England, residing at Sarnia, in the rovince of. Ontario and Dominion of Canada, have invented certain new and useful Improvements in Flushing Attachments for Sewers, of which the following is a specifi cation.

This invention relates to sewerage, and has more especial reference to an improved automatic liushing attachment for sewers* The primary object of the invention is to provide means whereby a sewer may be automatically flushed, by an abrupt intake of the water into the sewer having suficient force to dislodge such matter as has accumulated therein. f

The invention contemplates the provision of a cut-off valve associated with the sewer, whereby the fiow of water thereinto, may be controlled; a float supported upon a vertical standard connected with said cut-off valve and arranged within second float member carried by a pivotal arm supported upon the housing, and means arranged upon said arm engageablewith the upperV extremity of the vertical standard for permitting upward movement of the same, consequently, allowing the sewer to be flushed.

The annexed drawings and the following description set forth incertain detail, mechanism embodying theinvention, such disclosed means, constituting, however, but e various .mechanicalI forms in which the principle of the invention may be used. l

`lfnsaid annexed drawings 'Figure lis a vertical section in elevation' y Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1;

\ i Fig. 3 is a fragmental detail in section showing the position of the fioat members when operated; `and Fig. 4 is a section taken on theline 4 of Fier 1.

particularly to the drawings, wherein like reference characters designate like or corresponding parts throughout the several views thereof, V1t may bestated, that the device is preferably placed ina manhole, the side walls of which are `designated by the numerals land 2,'while a suitable housing; a'

' of the supporting rod 3 indicates a bottom or iiooring and i the y sewer connection.

eferring now to the present improvements, represents an elongated collar having arranged upon its opposite extremities, laterally distended Hanges 6 and 7, the former of which serve as means whereby the collar may be secured to the sewer connection, while the latter are adapted to receive in suitable openings 8, a threaded extrem` ity of `angular supporting' standards 9 and as at 11 and 1l. Locking nuts generally numbered 12 are threaded upon the extremities 11 and 11 andare arranged adj acent the upper andlower faces of the flange 7.

AA housing comprising a hollow cylindrical body 13 1s secured to the angular support- 10 by means of rivets v the said housing being' provided with a closedbottoin 15 and an Open top 16. drain Opening 17 is arranged in one side ofthe housing 13 thc purpose of which shall be subsequently apparent. Arranged interiorly of the said housing 13, preferably concentrically thereof, 1s a float 18, comprising a hollow cylindrical sheet metalV body having its top closed as at 19, while the bottom thereof is preferably left open. A bracing element 20 comprising an elongated strip of rigid material having arms 21 and 2l formed upon its opposite extremities is frictionally or otherwise secured tothe fioat by means of locking valve 25 is secured to nuts 24. A. conical the lower extremity 23, as at 26, preferably plvotal so as topermit the said conical valve to adjust itself in the seat as formed by the beveled portion 27, upon the inner face of the collar 5.

cross arm 28 having angularly disposed portions 29 and 29 is arranged over the top of the housing 13, the portion 29 being secured to said housing by means of rivets or other similar fastening devices as at 30. The cross bar 2 8 has arranged thereupon, upstanding ears 31 which are adapted to pivotally support a lever or supportingarm 32, as at 33, and, has arranged therein, an

llO

\ housing 13, `will then opening 3.4;. The lever 32 comprises a substantially inverted Ushapcd member having a flattened outer extremity 35, which has secured lthereto, as at `86, ,a -iioat 87, while the remaining extremity of the lever 32, has arranged therein, an inclined opening 38.

It will be noted that the upper portion voft-the 4stem 23 projects through the opening 34 at all times, whereby the `arm 28 consti.- tutes a guide for the stem. rlhe upper end ort the stem lprojects into the opening 3 8 o. the supporting lever 32, although because @jt the linclined construction of the opening 38, it is impossible for the stein to project through the opening 88 when the lever is in 1. horizontal plane.

In operation, water is permitted zto ilovv .into .the manhole whereupon, Awhen su'fiicient water has been .admitted .thereto to engage with the .float 37, .the arm 32 -will be moved upwardly. Upon continued rising off :the water, a portion thereof, will 4flow into the housing, thus, .exerting an upward pressure upon the 'float 18. However, due to the incl-ined arrangement ,oj lsaid opening 38, it will .be obvious, that the rod 12,3 will ib@ 19B@- vented from passing therethrough. As :the level of he water continues to rise, the lever .32 will be `moved into the position as ,shown .to advantage in Fig. 3 whereupon the inclined opening .38 will be alined with {the opening 34 as arranged in the cross bal Aand co nsequently, permit the rod 23 to be passed therethrough.

cause a sudden movement cal valve 25 will be `moved from. its seat in a `Similar manner, thereby permitting the abrupt inflow .of Athe water as .contained in the :manhole By 'this abrupt Aintake, suiii- .cient torce is embodied with the rush of water into the sewer connection t to dislodge such matter, as for instance mud or .the like, which has accumulated in the sewer, .and cause the same to be 4carried .on oli' into the inain. The water as contained .by `the -be `permitted to drain through `the opening 17, Yinto the manhole 'whereupon the valve .andfloats may be automatically reset for v.a subsequent iusliing.`

From the foregoing, it avill be vapparent that we have provided a simple and eliicient device whereby the sewer may lhe automatillushed Aand attention is also directed tothe tact, that the .amount of water as used during the iushing operation maybe varied by increasing .or 4decreasing the length of [the `angular supporting standards 9.and 10.

Other modes of applying the principle of our invention may be employed instead .of the one explained, change I.being made :as regards mechanism herein disclosed, provided the .means stated by ,any `ost the following claims, or .the equivalent of such stated means, be employed.

thereof, the .coni
